Notes Download Cassini++ from the link provided and extract the files to a directory on the same
machine that we are running Sharp Develop on.
14.1.3 Debugging an ASP.NET Application
First let us set a breakpoint in our application. Find the Default.aspx.cs file in our project and
open it in the text editor. Locate the Page Load method and set a breakpoint inside this method
on the Response.Write line (See Figure 14.2).

Now we need to configure the project to run Cassini when we debug our application. From
the Project menu select Project Options. In the options dialog select the Debug tab. Set the Start
Action to Start external program and enter the path to the Cassini executable. In the Start Options
enter the command line that will be passed to Cassini. The Cassini command line is of the form:
<Physical-path> <port> <virtual-path>

In the Figure 14.3 we can see an example command line passed to Cassini. In this case Cassini
will listen for requests on port 8080, the virtual path will be set to “/” and the physical path to
our project is specified by a using SharpDevelop property ${ProjectDir} which will be replaced
when we start debugging. We can put the full path to our project directory here instead of using
the ProjectDir property.
